i have a 1990 cherokee 4 door on about 8'' of lift and i want to see if there is anything i can do to avoid having drive line vibrations when i star driving it full time
i dont have to money for a slip yoke kit and would like to try to keep away from a t-case drop (to keep my good ground clearance)

ive heard from a buddy that you can use a yj yoke because it is longer than the stock cherokee one

 

That could work also if it is an Auto you can use a drive shaft out of a manual it is at least an inch longer. Also make sure shackles are in on your lift. Pinion angle is a big deal. Had the rear U-joint let lose once doing 65. lol (BANG BANG clink clink) Long walk to fetch my drive shaft out of the middle of the high way.

 

its an auto trans i will try to find a manual drive shaft
and get a yj yoke that should make the whole set up about 2'' longer
alos i have long shackles on the lift

thanks
